Is the BMW 335i reliable if you do proper maintenance?

The engine situation most 335is use the N54 (2007–2010) or N55 (2011–2013) twin-turbo inline-six. Both are excellent engines at heart, but they come with known weak points that will surface if ignored:

N54 common issues:

• High-pressure fuel pump (HPFP) failure — very common, but BMW extended warranty coverage on many
• Injector failure (carbon deposits, leaks)
• Wastegate rattle on turbos
• Valve cover and oil filter housing gasket leaks
• Charge pipe blowouts under boost

• N55 improvements:

  • Single twin-scroll turbo (simpler, more reliable)
  • Better HPFP design
  • Still prone to oil leaks and cooling system failures

    What "proper maintenance" actually means for a 335i

    This is where it differs from a Toyota. Proper maintenance on a 335i is more involved and more expensive than average:

    • Oil changes every 5,000–7,000 miles using BMW LL-01 spec full synthetic (0W-30 or 5W-30) — not the OEM 15,000-mile interval, which is too long for turbo engines
    • Cooling system overhaul around 80,000–100,000 miles — water pump, thermostat, and expansion tank are all plastic and will crack
    • Spark plugs every 30,000–40,000 miles (not the BMW-suggested 60,000)
    • Valve cover gasket — budget for this eventually, it's nearly universal
    • Charge pipe upgrade — a cheap silicone replacement prevents a frustrating roadside failure
